Comparison of the Effect of the Time Under the Three Primary Color Lighting of Led Production Before Scanning of Phosphorus Plates

Abstract

Purpose
 This study aims to compare the effect of light exposure in red, green and blue (RGB) colors prior to scanning of the PSP plates.
 Materials & Methods
 An Arduino-based system is produced for standardized light exposure to the irradiated PSP plates. The system consisted of an Arduino Mega 2560 developer board, 2 RGB LED light sources, a TSL2591 digital light sensor and a DHT11 temperature and humidity sensor. A light-tight platform is produced with additive manufacturing and electronical units are integrated into this platform. A two-step alloy was used to create contrast. PSP system (VistaScan, Dürr Dental, Germany) is irradiated with fixed parameters of 70 kV, 8 mA and 0.5 seconds. Scanning of the PSPs were delayed for 1-,3-,5-, and 10-minutes, and half of the active surfaces are exposed to RGB lights independently in full brightness (PWM) and calibrated with lux while the rest is protected. MGVs are measured in 6 regions per image. The MGV differences in regions between conditions were examined by Kruskal-Wallis test. A p-value
